    A bit of an experiment here as I’ve never tried linking a Facebook video to my RMweb thread. 


    This is from the Mallaig Heritage Centre and show ‘Blaven’ being launched from the slip that features on my layout. It’s a bit fuzzy but I think it’s an absolutely wonderful little video.

     

    Interesting.

    I bet they were glad when they got the engine started.

    Here is another of those woke baby millennials 'elf 'n safety freaks complaining about the sort thing that we used to deal with in ease in our day. Needs to grow up and start taking responsibility. I blame the parents myself.

     

    Minding the gap: 'It's a scandal, it's a death trap'

     

    A candidate for this


    Doesn’t look very woke baby millennial to me.

    Not quite sure what it has to do with WCRC’s battle with the ORR

    My postie comes everyday Mon - Sat, usually around 11.30.  He/she does the walking letter round then shortly afterwards brings any parcels in the van. 


    Ours does the parcels first then the walking letter round.

    Could this, I wonder, be the Northumberland/Durham equivalent of the Cornwall/Devon cream scone wars?

    I managed to get myself ready and set off early for my 3pm in Leigh on Sea for my hearing test. The sound proof box was faulty but they have portable units for home visits. Anyway the test went well and pretty well confirmed by own belief/observations of the state of my hearing over the last year. It was however not just a case of boosting the default amplification but tweaking certain frequency bands. 
    I got a cup of tea and a biscuit too!

    The ‘tweaking of certain frequency bands’ in some modern hearing aids outperforms many top of the range graphic equalisers that cost and arm and a leg a few years ago.
     

    Apart from the overall amplification I notice a huge improvement un the clarity of what I hear.  My (lack of) frequency response is a result of, and typical of, me having measles as a youngster.

    IIRC, the average European of today has something like 3 - 5% Neanderthal DNA.

    That’s most reassuring given that we share about 50% of our DNA with a banana.

    at some point I find the solutions more obnoxious than the problem and would prefer to live with the risk


    That is fair enough if it were only you involved and happy to take the risk.  Others (the majority?) might prefer to have mitigations put in place to reduce that risk. I know you were speaking in more general terms, but  I wouldn’t like to be the one hit by a moving open door because someone else found fitting CDL ‘obnoxious’.

    BoD I thought Clockman was  referring to the arrangement where a relay is energised then one of its own set of  contacts maintains the energy to the coil.

    Such an arrangement  requires a current  through the coil.  The interruption of that current by pressing a normally closed push button then switches the relay off.

     

     

    Are you referring to some kind of mechanical  latching? How is such a relay then switched off?


    Others have replied but RS-online has a useful explanation - again, as others have said, it may be a case of the terminology being used.

    A latching relay requires a constant current which the cdu  won't give.  I suppose  it would work with a twin coil relay of some sort  using a second supply to keep it latched. 


    Sorry Colin, a latching relay does not require a constant supply once activated - hence the term latching. They are switched on and off by pulses of current.

    Wasn't certain how to rate your post but in the end I think anyone who can do the pass without an engine thingy deserves a might big round of applause!


    Note I did say once.
